According to the manual for the four channel RF Wireless controller, A=Common, B=Normally Open, C=Normally closed. I wired up my unit where (+) goes to to C= normally closed. (-) goes to B= Normally Open, and A=common goes to the motors. I had the unit wired up and did a continuity check. I put a probe on the (+) wires going into the unit. I get a signal on each positive input (terminal C). but I get no positive signal on A (common). But when I put a signal in on terminal B (my negative side), I also get a signal on my common side. It sounds like you manual is backwards. Can you verify? Could there have been a design change and the manual does not reflect that?
Thanks!

You got to tell me which one you have as we have a couple model, even though they are using the same chipset "1527" Also, you can double check it by using a digital meter to check the continuity.

Model 4A or catalog # ERF-4A4331527M . Does that help?
